Patent number: 9602440Abstract: To re-establish a direct tunnel between an access node and a gateway router in a wireless network, a control node that provides mobility management on behalf of mobile stations detects restart of the gateway router. In response to detecting restart of the gateway router, the control node sends context information regarding a previously established direct tunnel to the gateway router to enable the gateway router to re-establish the direct tunnel.Type: GrantFiled: February 17, 2016Date of Patent: March 21, 2017Assignee: Apple Inc.Inventors: Sourabh Anpat, Laurence Lautier, Michael Brown

Patent number: 9253081Abstract: In one embodiment, a machine type communication (MTC) device can receive registration associated with a new device upon the new device registration for a computer network. The MTC device can further determine a machine-to-machine (MTM) service class for the new device based on the registration data with the service class associated with at least one network route for messages destined for the new device. The MTC device can further receive a trigger message destined for the device and route the trigger message according to the network route associated with the determined MTM service class.Type: GrantFiled: November 15, 2012Date of Patent: February 2, 2016Assignee: Cisco Technology, Inc.Inventors: Sourabh Anpat, Mahbubul Alam

Patent number: 8385903Abstract: Systems and methods for transferring a session or components of a session in a communication network are provided. The components of the session include media flows and control over the media flows. The user can initiate a transfer of a existing session with a mobile device such as user equipment (UE) to one or more devices that may lead to fan-out or fan-in to multiple devices. This can include separating the delivery of media from the control of the delivery. For example, a UE can be designated a controller to control another UE, such as a television (TV). In providing the capability to transfer these sessions, a gateway is used to implement network functions that allow the streaming to be controlled and delivered to the respective UEs. In some embodiments, the gateway can be flexible and its operation modified according to messages it receives.Type: GrantFiled: January 12, 2010Date of Patent: February 26, 2013Assignee: Cisco Technology, Inc.Inventors: Rajat Ghai, Sourabh Anpat

Publication number: 20120252481Abstract: This disclosure relates to a system and method for providing machine to machine communication in a communication network. Although machines are ever more capable of sensing and processing information, machines are expected to garner even more intelligence by autonomously communicating the sensed and processed information with other machines. Therefore, machine to machine (M2M) communication is emerging as an important application of a communication network. Despite the opportunity, accommodating a large number of machines in a communication network is a challenge for network operators. This disclosure provides systems and methods for efficiently accommodating M2M communication in a communication network.Type: ApplicationFiled: April 1, 2011Publication date: October 4, 2012Applicant: CISCO TECHNOLOGY, INC.Inventors: Sourabh ANPAT, Nirav SALOT

Patent number: 8055774Abstract: An IMS system including a Home Subscriber Server including data for terminals connecting to the IMS. The Home Subscriber Server being arranged to transmit a reset message to components such as application servers and S-CSCF in the IMS when it undergoes a reset. The receipt of a reset message causing the component to mark the terminals that the HSS stores the data for as not confirmed. The component then, either automatically or in response to a message, transmits a message to the Home Subscriber Server to request user profile data for a user terminal connecting to the IMS or accessing services from the IMS.Type: GrantFiled: July 14, 2008Date of Patent: November 8, 2011Assignee: Genband US LLCInventors: Ricky Kaura, Sourabh Anpat
